Online or e-banking has been adopted as key banking innovation in Uganda adopted by all financial institutions in the country. This research explored the state of e-banking and its efficacy in Uganda banking industry. A correlation analysis approach was adopted for this research. In Uganda, the banking sector has been liberalized with telecommunications allowed to effect e-banking and ecommerce transactions. The study concentrated on the periods of years 2011/2012 and 2012/2013. Findings from this research revealed that BOU uses UNISS for real time gross settlement (RTGS). Since its adoption a +1 coefficient correlation was realized. With the use of mobile money, also a +1 coefficient correlation was achieved for the period under consideration. As regards the use of e-cheques, there was a drop reflected by -2.8 percent which could have been attributed to perception of the users, though there was a +1 coefficient correlation when considering e-cheque transactions and the monetary value. The use of EFT in Uganda generated a +1 coefficient correction considering the number of users and the monetary value involved. Bank of Uganda should work hard and make or go live with electronic banking supervision software which would aid them with their supervisory roles.

There hardly have been support policies for small wholesale vendors or any materials such as proper statistical standards and figures compared to diversity of support policies and size of budget for small and medium manufacturing business. The biggest concern coming from it is that there have never been any policies for small and medium wholesale vendors. This study proposes some ways to improve support policies through investigating the current status of those vendors as their true values haven't been properly recognized, while diverse support systems have been devised for manufacturing business thanks to the traditional industrial development process. According to the study on support policies for domestic and international small and medium wholesale vendors, I realized that those vendors need a policy to ensure them to be promptly adjusted to the rapidly changing distribution environment and to be competitive to access to the global distribution market to finally become hidden champions through systematical operations of small and medium wholesale vendors and implementing educational business through sales management. Therefore, I propose five ways to improve support policies for small and medium wholesale vendors by considering social and economic value, systematizing small wholesalers and scaling small and medium wholesale vendors, reinforcing support for wholesalers, support policies for new online market opening and offline market opening.

GARCH-X(1, 1) model specifies that conditional variance follows an AR(1) process and includes a past exogenous variable. This study proposes a new class from that model by allowing a more general (non-linear) variance function to follow an AR(1) process. The functions applied to the variance equation include exponential, Tukey's ladder, and Yeo-Johnson transformations. In the framework of normal and student-t distributions for return errors, the empirical analysis focuses on two stock indices data in developed countries (FTSE100 and SP500) over the daily period from January 2000 to December 2020. This study uses 10-minute realized volatility as the exogenous component. The parameters of considered models are estimated using the adaptive random walk metropolis method in the Monte Carlo Markov chain algorithm and implemented in the Matlab program. The 95% highest posterior density intervals show that the three transformations are significant for the GARCHX(1, 1) model. In general, based on the Akaike information criterion, the GARCH-X(1, 1) model that has return errors with student-t distribution and variance transformed by Tukey's ladder function provides the best data fit. In forecasting value-at-risk with the 95% confidence level, the Christoffersen's independence test suggest that non-linear models is the most suitable for modeling return data, especially model with the Tukey's ladder transformation.

고속 데이터 전송이 가능한 장점 때문에 OFDM 통신 방식은 4세대 통신 방식으로 주목 받고 있다. OFDM은 이러한 고속 무선 데이터 통신을 구현하기 위해서는 고성능의 FFT(Fast-Fourier-Transform) / IFFT(Inversion FFT) 프로세서를 필요로 한다. 현재 OFDM은 DSP(Digital Signal Processor)로 구현되고 있지만 많은 전력 소모의 단점을 가지고 있다. 이러한 단점을 보완하기 위해 Current-mode FFT LSI가 제안되었다. 본 논문에서는 저전력 OFDM용 IVC(Current to Voltage Converter)를 설계한다. 시뮬레이션 결과 설계된 IVC는 FFT Block의 출력이 $7.35{\mu}A$ 이상일 때 3V 이상의 전압을 출력하고, FFT Block의 출력이 $0.97{\mu}A$ 이하일 때 0.5V 이하의 전압을 출력하였다. 설계된 IVC로 저전력 Current-mode FFT LSI의 동작이 가능하게 되며, 전류모드신호처리는 차세대 무선 통신 시스템의 발전에 기여할 것이다.

Utilization of information and communication technologies is commonly accepted as important to value creation in the knowledge economy. Nevertheless, empirical findings from our business case studies often show that while sophisticated technological tools may be developed, the potentials are not realized. It is evident that technology is subject to adaptive and emergent strategies of use, diverging from the original intention. Within this space of opportunities, we elaborate the importance of constructing strategic concepts as communication tools to support organisational implementation of technologies. We use the concept of organisational implementation as a way of taking the technology into use in order to support changes and value creation in the user organisation. In this paper we present our findings related to how use and experiences are conditioned by the users' expectations. We have conducted a business case study in order to understand and explore how users employ and use a particular wireless technology infrastructure. On behalf of the infrastructure vendor, we have studied three different organisations that use this technology. The overall research goal of our joint research project was to find out what is good use and for whom. We find that users struggle to go beyond the expectations they had when they were conceptualising and telling us about their practice. We have good indications that a narrowed consciousness was also conditioning the users' use of the technology. In this paper we draw the conclusion that technological implementations towards changing work practices and value creation must not be viewed by the company solely as a knowledge acquisition process, but as a process of knowledge creation. Organisational implementation is an ongoing process, a learning process at both the organisational and individual level. Flexible tools and technologies are constituted and shaped in interaction and communication in the workplace. Based on that knowledge, we build up an argument for an organisational implementation framework, including strategic discussions, learning spaces, and concept constructions.

공자는 춘추시대라는 혼란한 현실을 극복하기 위하여 인간의 내면적 가치에 대한 성찰뿐만 아니라, 그 가치를 어떻게 밖으로 끌러낼 것인가, 그리고 어떻게 인간관계를 맺을 것인가에 대하여 끊임없이 고민하였다. 공자가 언급한 '화이부동'의 정신은 인(仁)의 실천이라는 타자와의 올바른 관계 맺기를 위한 원론적인 의미를 던져주고 있다. 화이부동의 정신은 도덕적이며 공적인 그리고 중용적인 가치를 추구한다. 이는 개인이나 사회공동체 더 나아가 자연과의 관계에 있어서 화합과 공존을 모색하기 위한 것으로, 군자는 이러한 화이부동의 정신을 구현한 인격자이다. 화이부동의 정신은 현 시대의 화두인 '더불어 살기'란 사회 통합에 있어서 많은 점들을 시사하고 있다. '더불어 살기'가 구체화될 수 있는 대상은 다문화가정이나 북한이탈주민 등 우리 사회의 소수자 집단이며 권력이나 이익으로부터 상대적으로 소외된 사람들이다. 화합과 공존을 모색하는 이러한 열린 마음은 더 나아가 생태계와 모든 자연을 포괄하는 환경문제에 있어서도 중요한 시사점을 주고 있다.

This study considers the expressive types of 'Glocalism' trends and its inherent aesthetic characteristics through the analysis of flight attendants' uniform design. The following is the conclusions regarding the glocalism trend according to the analysis of airline uniform design that reflect it. First, the design approach was developed appropriating the whole or parts of traditional attire and applying decorative items in terms of a formal aspect. Secondly, the colors of the airline's homeland symbols or natural environment were used while, thirdly, the fabrics represent glocalism by employing folk elements of the region and patterns of nature for a uniform design. Induced from these design analyses, the aesthetic characteristics of airline uniforms reflecting glocalism are traditionality, naturality, and compromisability. To begin with, traditionality is what is realized in interpreting the historical aesthetics in a contemporary perspective, contributing in inspiring the historical value of the homeland and contributing to the establishment of identity by applying forms and colors of traditional garments with folk patterns on a uniform design. In addition, naturality means the reorganization of unprocessed pure nature, expressing the image of nature through colors taken from the natural environment or motifs of the regional plants. Finally, combining general sensibilities with diverse cultural features, compromisability is realized as a modern design which combines a standardized uniform with the aesthetic components of the local environment and traditional garments.

The Legal Floor Area Ratio (L-FAR) has been used as a major urban planning tool for efficient management of land use, landscape, and density. The Developed Floor Area Ratio (D-FAR) in each parcel is realized by such physical and institutional factors as urban tissue, local characteristics, and zoning with the L-FAR. The Achieved Floor Area Ratio (A-FAR), the ratio of the D-FAR to the L-FAR, is the relationship between realized density and the intended/desired outcomes of the regulations. The A-FAR informs the efficiency of L-FAR and its effect on parcels, and is an indicator of the demands of real estate developments under the zoning regulation. This study used detailed data of each parcel's characteristics, including parcel size, road width, and the number of roads bordered by a parcel, to identify the influencing factors on A-FAR. This analysis confirmed that the parcel size has a non-linear negative effect in the residential zone but a linear positive effect on A-FAR in the commercial zone. The width of the parcel's frontage in the commercial zone has a positive effect on the value, while in the residential zone the narrower width has higher A-FAR. In Seoul, the residential zone has higher A-FAR than the commercial zone, which means that the former has a relatively higher development pressure but a lower designated L-FAR. This result reflects that Seoul's residential zone absorbs the demand of commercial uses because of the significant permitting of mixed land use and has high-density residential buildings.

A high-speed traveling-wave photodetector (TWPD) with an InGaAs absorber is designed and realized. The bandwidth of the TWPD is measured using electro-optic sampling techniques. The bandwidth is 410 GHz, which shows that the RC limitation is overcome. While the TWPD shows a low responsivity of 0.06 A/W at 1,550 nm, this value can be improved through further optimization of the structure without a sacrifice in bandwidth.

In the present work, a seat suspension system adopting semi-active damper is evaluated for driver's ride quality. A cylindrical type of ER(electrorheological) damper is designed and manufactured for the seat suspension of heavy vehicles. The governing equation is derived under consideration of human vibration. A sliding mode controller is then synthesized and experimentally realized on the manufactured ER seat suspension while a driver is sitting on the controlled seat. Ride quality is evaluated by fatigue decreased proficiency boundary, vibration dose value and crest factor utilizing weighted-acceleration according to ISO2631.
